“未使用的全局选项”错误消息

我正在努力做数学作业，我的教授为我们提供了模板的代码。

我过去完成每项作业都是将其复制并粘贴到新文档中，然后开始添加我的代码，没有任何问题。

但是，这次当我粘贴模板代码后尝试编译时，我收到一条错误消息，提示“未使用的全局选项”。我该如何修复此问题？

以下是模板代码：

答案1

你得到的不是一个错误消息。相反，它只是以下内容警告信息：

LaTeX Warning: Unused global option(s):
    [onesided].

你有两个选择（双关语）：

  • 忽略无害的警告。

  • 删除未使用的全局选项，即更改指令

    \documentclass[12pt,reqno,onesided]{article}

    到

    \documentclass[12pt,reqno]{article}

最后的评论：你的导师模板的代码效率很低，并且包含毫无意义的指令，例如\vfill\eject紧接着之前\end{document}。如果你遇到各种随机的警告消息，我不会感到惊讶。

答案2

向@Mico 添加第三个解决方案——您可以替换拼写错误。实际上，正确的类选项应该是oneside（不是onesided您的教授所说的）。oneside恰好是article和report类的默认选项。由于可以安全地省略默认选项，因此我的建议也可以安全地减少并追溯到 Micos 的第二个解决方案。

但是，由于我们如今浪费了大量的资源，包括纸张，我建议你忽略教授的命令，将文档的第一行改为

\documentclass[12pt,twoside]{article}

编辑：试图使布局的要点更加清晰

这会将文档的布局更改为双面，即准备在一张纸上打印两个逻辑页面的文档，为您（和我们的环境）节省大约 50% 的纸张使用量。显然，您的打印机也必须支持双面打印。
